This is an adaptation
This is an adaptation of a story by Roger Moore. I believe that Moore's story is a great example of the David Lynch style of storytelling. The story is very complex and the characters are all very complex. I won't spoil the movie for any of you, but if you haven't seen it, so be prepared. It is a great story, but if you don't see it, then stay away.
This is an adaptation of a book which was published in the 1930s. The book is mainly about the time of the Second World War.
